摘要
比较了正常灌溉和干旱处理条件下新疆21个春小麦品种的实际产量结果,初步明确新春2号、新春6号、新春10号、新春12号属正常灌溉高产且干旱处理稳产又抗旱的类型。通过对产量和主要农艺性状抗旱系数和抗旱指数的比较分析,认为产量抗旱指数比抗旱系数更能反映品种的抗旱性;虽然产量抗旱指数与干旱处理的产量极显著相关,但仍然不能完全反映每个品种干旱处理的产量;不同品种抗旱性鉴定的结论,应以干旱处理产量为主。
Comparative analysis was conducted on the yield of 21 spring wheat varieties under drought and irrigation conditions in Xinjiang,including Xinchun2, Xinchun6, Xinchun10 and Xinchun12 whose yield was higher under the two conditions.It was determined preliminarily that the 4 varieties had stronger drought resistanc. Drought resistance coefficient and index of yield and important economic characters were compared and analysed . The result showed that drought-resistance index was superior to drought-resistance coefficient in representing drought-resistance. Although the drought-resistance index of yield was significantly relative to the yield of drought condition ,it could not completely represent product of drought condition. The identification of different wheat variety drought-resistance should take the yield of drought condition as the dominat factors.
